Product Overview

The LT1511ISW#PBF is a constant-current/constant-voltage 3A Battery Charger with input current limiting. This current mode PWM battery charger is the simplest, most efficient solution to fast charge modern rechargeable batteries including Li-ion (Li-ion), nickel metal-hydride (NiMH) and nickel-cadmium (NiCd) that require constant-current and/or constant-voltage charging. The internal switch is capable of delivering 3A DC current (4A peak current). Full-charging current can be programmed by resistors or a DAC to within 5%. With 0.5% reference voltage accuracy, the LT1511 meets the critical constant-voltage charging requirement for Li-ion cells. A third control loop is provided to regulate the current drawn from the AC adapter. This allows simultaneous operation of the equipment and battery charging without overloading the adapter. Charging current is reduced to keep the adapter current within specified levels.
  • Adapter current loop allows maximum possible charging current during computer use
  • Precision 0.5% accuracy for voltage mode charging
  • 5% Charging current accuracy
  • Adjustable undervoltage lockout
  • Automatic shutdown when AC adapter is removed
  • 3µA Low reverse battery drain current
  • Current sensing can be at either terminal of the battery
  • Charging current soft-start
  • Shutdown control
